Hiroshi is my best friend.

He faced difficulties with the spirit of 'one eye, two feet, three gallbladders, four strengths'.

Chlorofluoromethane is one of the substances that contribute to the destruction of the ozone layer.

The house over there is very big.

He achieved great success in his business, but as the proverb 'A thousand gold pieces' fur is not from one fox's armpit' suggests, it was not something he obtained overnight.

The encounter with him can be said to be 'the events of today are destined by the past.'

He tried to work hard and study at the same time, and in the end, he experienced the lesson of 'He who chases two hares catches neither.'

His success is an example of the proverb 'one general achieves success at the cost of ten thousand bones'.

He said, 'It's difficult to make a life,' explaining the phrase 'When a man steps over the threshold, he has seven enemies.'

He said, 'Man shall not live by bread alone,' teaching me that spiritual satisfaction is also important.
